From: Sean Christopherson Date: Wed, 23 Sep 2020 18:31:12 +0000 (-0700) Subject: KVM: VMX: Rename ops.h to vmx_ops.h X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5a085326d51d0c92bc5c1f62d60dcf3db450af69;p=linux.git KVM: VMX: Rename ops.h to vmx_ops.h Rename ops.h to vmx_ops.h to allow adding a tdx_ops.h in the future without causing massive confusion. Trust Domain Extensions (TDX) is built on VMX, but KVM cannot directly access the VMCS(es) for a TDX guest, thus TDX will need its own "ops" implementation for wrapping the low level operations.
